BACKGROUND

With rapid development of electronic technologies, electronic terminals with a display screen, such as a smartphone, a tablet computer, and a smart television, are widely applied in people's daily life. For the sake of beauty, wallpaper is usually set in a lock screen interface, a home interface, and the like of an electronic device. The wallpaper is classified into static wallpaper and live wallpaper. A user may set a specific picture as the wallpaper, or set a picture set that includes a plurality of pictures as the wallpaper, and the plurality of the pictures may be switched according to a particular rule.

However, the wallpaper currently set in the electronic terminal is usually a picture obtained from the Internet or a picture taken by using a camera in the electronic terminal, and is relatively singular. Therefore, user experience is relatively poor.

The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

The embodiments of the present invention may be implemented based on a single electronic terminal, or may be implemented based on a schematic architectural diagram of a data processing system provided in an embodiment of the present invention shown in FIG. 1. The data processing system may include at least one electronic terminal 110 and/or at least one server 120. The electronic terminal may include but is not limited to a smartphone, a tablet computer, a desktop computer, a mobile computer, a smart television, a smart band, a personal digital assistant (Personal Digital Assistant, PDA), a media playing device, and the like. Communication may be performed between electronic terminals 110, and between the electronic terminal 110 and the server 120 by using a wireless network or a wired network. The server may be a server of various network platforms, for example, a social network platform such as WeChat, Tencent QQ, a microblog, a blog, MSN (Microsoft Service Network), or Facebook, and for another example, a network platform that can log in to a user account, such as Vmall (English: Vmall), Google, Amazon, or YouTube.

It may be understood that the electronic terminal 110 may record user data when a user uses the electronic terminal 110, and the user data may include information about an operation event generated when the user operates the electronic terminal. For example, the operation event may be an operation event for the user to start an application program on the electronic terminal 110, and corresponding operation event information may include a time and a location for starting the application program, and/or a quantity of historical start times, or the like. For another example, the operation event may be a retrieval event of a target keyword, and corresponding operation event information may include a retrieval time, a location, and/or a quantity of times, or the like of the target keyword. The user data may further include information that is associated with the user account and that is based on at least one network platform, and the network platform may include the social network platform such as WeChat, Tencent QQ, or Facebook, or may be the network platform that can store user information, such as Vmall, Google, Amazon, or YouTube. The user data may be the user information under the user account, for example, user's personal information recorded under a user account of WeChat, which may include a browsed website, a chat record, contact information, or the like; and for another example, browsed commodity information under a user account recorded on the network platform “Vmall”. The user data may be the information associated with the user account, for example, information published in a friend account that is associated with the user account of WeChat, which is, for example, information such as news update and an address that are published by a friend.

It may be understood that, the electronic terminal 110 in “the operation event information of operating the electronic terminal 110” by the user may be the electronic terminal described in an execution body of the present invention, or may be an electronic terminal associated with the electronic terminal described in the execution body of the present invention, for example, the tablet computer with the same login account as a mobile phone serving as the execution body, or the smart band, a smart television, and the like that are bound to the mobile phone serving as the execution body. The user may perform an operation on different electronic terminals 110, to generate and record the operation event information, and the operation event information recorded on the electronic terminal may be transmitted between the electronic terminals 110 by using a communication connection.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a data processing method according to an embodiment of the present invention. The data processing method includes the following steps.

Step S210. An electronic terminal obtains target data, where the target data includes at least one data item, and the target data includes operation event information of operating the electronic terminal by a user, or information that is associated with a user account and that is based on at least one network platform.

Specifically, the electronic terminal may obtain the target data, where the target data is user data and may include the operation event information of operating the electronic terminal by the user, or the information that is associated with the user account and that is based on the at least one network platform. The data item is a minimum unit discussed in a data structure, is a most basic and indivisible named data unit in a data record, and is a minimum identification unit having an independent meaning. The data item may be one of or a combination of a letter, a character, an image, a number, or the like. For example, the target data is a quantity of historical start times of an application program. In this case, the data item includes a quantity of historical start times of a target application program, for example, a quantity of historical start times of an application program “Vmall”.

It may be understood that the operation event information generated when the user operates the electronic terminal may be: each website visited by the electronic terminal and a time, a location, a quantity of historical visiting times, and the like of visiting each website; each keyword retrieved on the electronic terminal and a retrieval time, a location, retrieval frequency, and the like of each keyword; information recorded during a jump from one application to another application in the electronic terminal; a time, a location, and the like of opening a preset-type file such as an ebook or audio file by the electronic terminal; and historical duration and the like of running each application by the electronic terminal. The information associated with the user account may be: information published by the user by logging in to the network platform, for example, personal information, a log, and a geographic location; or a contact associated with the user, for example, a friend of the user on a network dating platform such as WeChat or Tencent QQ, where the friend can log in to the network dating platform to publish his/her personal information, a log, a geographic location, an application in use, and the like, and the user has a permission to obtain the information; or a browsed commodity, a purchased commodity, or the like under a user account of a network platform such as a shopping website.

Optionally, an implementation of obtaining the target data by the electronic terminal may include: obtaining, by the electronic terminal, the user data; and selecting the target data based on the user data, or calculating the target data based on the user data. For example, the user data is ages, genders, geographic locations, and quantities of historical chat times of all contacts associated with the user. The electronic terminal may select the geographic locations of all the contacts based on the user data and use the geographic locations of all the contacts as the target data, and the data item is a geographic location of any contact. For another example, the electronic terminal may collect statistics on the user data by age and obtain a quantity of contacts born in each time period as the target data, and the data item may include a quantity of contacts born before 1980, a quantity of contacts born between 1980 and 1990, a quantity of contacts born between 1990 and 2000, and a quantity of contacts born after 2000.

Optionally, when the target data is stored in a server, another implementation of obtaining the target data by the electronic terminal may include: sending, by the electronic terminal, a data obtaining instruction to the server, where the data obtaining instruction is used to request to obtain the target data, and after receiving the data obtaining instruction, the server sends the target data to the electronic terminal. For example, the electronic terminal sends the data obtaining instruction to a server on which the network platform “Amazon” is located, and requests to obtain a name and an amount of a purchased commodity.

Step S220. Convert the target data into a data image by using a data visualization technology, where the data image includes at least one graphic element, and the graphic element is in a one-to-one correspondence with the data item.

Specifically, the data visualization technology means that data in a data set is represented in a form of a graphic image. The data visualization technology may be classified into a geometry-based technology, a pixel-oriented technology, an icon-based technology, a hierarchy-based technology, an image-based technology, and a distributed technology according to a principle of visualization. A basic idea of the data visualization technology is that each data item in a database is represented as a single graphic element, and a large quantity of data sets constitute the data image. In addition, various attribute values of data may be expressed in a form of multidimensional data, and the formed data image may be observed from different dimensions, so as to facilitate deeper observation and analysis of the data. It may be understood that the data image may be a two-dimensional planar image or a three-dimensional stereoscopic image.

In this embodiment of the present invention, the data item may include a geographic location of a target contact, and the target contact is a contact associated with the user account. Step S220 may specifically include: adding the graphic element to the geographic location on a preset map to form the data image, so as to visually display, by using wallpaper, the geographic location of the contact associated with the user.

Specifically, the target contact may be the friend of the user on the network dating platform such as WeChat or Tencent QQ, and the friend may share his/her geographic location by using the network dating platform. The user may obtain geographic location information shared by the friend, add the graphic element to the geographic location of the friend on the preset map with reference to a map application, and add graphic elements to geographic locations of all friends, so as to form the data image. The preset map may be a map of a preset area specified by the user, for example, a “map of Guangdong province”. The geographic location may be determined longitude and latitude, or may be a location range, for example, a cell, a trading area, and an office building in which the friend is located. The graphic element may be a high-brightness point, or may be an icon used to mark the geographic location.

Referring to FIG. 3, FIG. 3 is a schematic diagram of a first data image according to an embodiment of the present invention. In the data image shown in FIG. 3, a night map is used, lighting is simulated by using a high-brightness point, and the high-brightness point is marked at a geographic location of a friend, so as to form a data image, and a distribution status of the address position of the friend may be displayed based on a quantity and density of the high-brightness points in the area.

In this embodiment of the present invention, the data item includes a contact who uses a target application and a total quantity of users of the target application. Step S220 may specifically include: setting, based on the total quantity of the users of target application, a parameter for the graphic element corresponding to the data item, and associating the contact who uses the target application with the graphic element for which the parameter is set, to form the data image, so as to visually display a total quantity of users of each application in contacts and a contact included in the total quantity of the users. The parameter may be an area, a volume, a length, position coordinates, or the like.

Specifically, a target contact may be the friend of the user on the network dating platform such as WeChat or Tencent QQ, and the friend may share his/her application for use by using the network dating platform. The user may obtain a name of the application shared by the friend, and separately count a quantity of friends using each application, to obtain a total quantity of users of each application. Then, the user uses a sector of a particular radius as the graphic element, and uses the total quantity of the users of each application to separately determine an area or an angle of each sector, so as to form a pie chart. Alternatively, the user uses a rectangle of a particular width as the graphic element, and uses the total quantity of the users of each application to separately determine an area or a length of each rectangle, so as to form a bar chart. Alternatively, the user uses a point as the graphic element, and uses the total quantity of the users of each application to separately determine a location of each point, so as to form a line chart, and so on. Optionally, the graphic element for which the parameter is set may be associated with each contact who uses a corresponding application, and an association manner may be displaying, on the graphic element, information such as a portrait icon or a name of each contact who uses the corresponding application, or may be connecting, by using a line segment, the graphic element and the portrait icon and the name of each contact who uses the corresponding application.

Referring to FIG. 4, FIG. 4 is a schematic diagram of a second data image according to an embodiment of the present invention. In the data image shown in FIG. 4, a pie chart is used to show a total quantity of users of each application among friends and friends who use each application, and the quantity of users of each application may be intuitively described by using an area size of each sector in the pie chart.

In this embodiment of the present invention, the data item may include a preset parameter corresponding to a target operation event. The data processing method may further include: detecting, by the electronic terminal, whether the target operation event occurs; and when the target operation event is detected, updating the preset parameter, in the data item, corresponding to the target operation event.

Specifically, the target operation event may be an operation event of starting the target application program by the user on the electronic terminal, and a corresponding preset parameter may include a time and a location for starting the application program, and/or a quantity of historical start times. For another example, the target operation event may be a retrieval event of a target keyword, and a corresponding preset parameter may include a retrieval time, a location, and/or a quantity of times, or the like of the target keyword. The electronic terminal may monitor a user operation in real time, and when detecting the target operation event, the electronic terminal updates the preset parameter corresponding to the target operation event, that is, updates the target data, and further updates the data image in real time.

Optionally, the target operation event may be an event of visiting a target website, and the preset parameter includes an identifier of the target website and a quantity of historical visiting times of the target website. Step S220 may include: determining a parameter for the graphic element based on the identifier of the target website and the quantity of the historical visiting times, where the parameter includes at least one of a name, a size, chrominance, and transparency, and further setting, according to a preset rule, position coordinates of the graphic element for which the parameter is determined, to form the data image, so as to visually display a quantity of historical visiting times of each website visited by the user.

The target website may be a website that has a preset domain name, for example, a domain name “huawei.com/cn” of Huawei website, and a domain name “sina.com/cn” of Sina website. The electronic terminal may identify, based on a website, a domain name to which the website belongs, and the identifier of the target website may be a name, a domain name, a logo (logotype), or the like of the website. The graphic element may be a geometric pattern or the like. For example, the electronic terminal may use the website name, the domain name, or the like corresponding to the target website as the name of the graphic element, and determine the size of the graphic element by using the quantity of the historical visiting times of the target website.

Referring to FIG. 5, FIG. 5 is a schematic diagram of a third data image according to an embodiment of the present invention. In the data image shown in FIG. 5, starry sky is simulated, a circle is used as the graphic element, the quantity of the historical visiting times of the target website is used to set a radius of the circle, and the quantity of the historical visiting times is positively correlated with the radius of the circle. The domain name of the target website is used as a name of the circle, various graphic elements are randomly distributed, and the quantity of the historical visiting times of each website visited by an electronic terminal may be intuitively described by using a size of the circle.

Optionally, the target operation event may be a retrieval event of a target keyword, and the preset parameter includes retrieval frequency of the target keyword. Step S220 may include: setting a target font size for the target keyword based on the retrieval frequency, and using the target keyword of the target font size as the graphic element, to form the data image, so as to visually display the retrieval frequency of each keyword retrieved by the user.

Referring to FIG. 6, FIG. 6 is a schematic diagram of a fourth data image according to an embodiment of the present invention. In the data image shown in FIG. 6, keywords of the target font size are randomly distributed, colors of the keywords are randomly set, and a field concerned about by the user is intuitively described by using a font size of a keyword.

Optionally, referring to FIG. 7, FIG. 7 is a schematic diagram of a fifth data image according to an embodiment of the present invention. The target operation event may be a jump event from a first application to a second application, and the preset parameter includes an identifier of the first application, an identifier of the second application, and a start time of the second application. Step S220 may include: arranging, in a preset direction, the identifier of the first application and the identifier of the second application in a sequence of a first-time start time of an application, and further using an arc that connects the identifier of the first application and the identifier of the second application as the graphic element, to form the data image, so as to visually display a jump situation of the user using the application program. The identifier of the application may be a name, an icon, or the like of the application.

Optionally, the target operation event may be an opening event of a preset-type file, the preset-type file may be the ebook, the audio file, and the like, and the preset parameter includes a cover picture corresponding to the preset-type file. Step S220 may include: using a cover picture of a recently opened preset-type file as the graphic element, to form the data image, so as to visually display a recently read ebook or a recently listened audio file of the user. A file type may be determined by using a file format, for example, a file in a format such as “txt” and “Pdf” is an ebook, and a file in a format such as “MP3”, “avm”, “mvk”, and “fly” is an audio file.

Referring to FIG. 8, FIG. 8 is a schematic diagram of a sixth data image according to an embodiment of the present invention. The preset-type file is the ebook, and the preset parameter is a cover picture corresponding to the ebook. The electronic terminal monitors an opening operation of the ebook in real time, and the preset parameter is updated in real time to a cover picture of a recently opened ebook. The electronic terminal uses the cover picture of the recently opened ebook as the graphic element, to form the data image.

Step S230. Set the data image as wallpaper.

Specifically, the electronic terminal sets the data image as the wallpaper, and the wallpaper may be displayed in a home interface of the electronic terminal, or may be displayed in a lock screen interface of the electronic terminal.

Optionally, step S230 may specifically include tailoring the data image based on a preset size, and setting a tailored data image as the wallpaper.

An implementation of tailoring the data image based on the preset size may be: the electronic terminal obtains a size of a display screen, and tailors the data image to the preset size that matches the size of the display screen. An implementation of tailoring the data image based on the preset size may further be: obtaining a tailored area selected by the user, and tailoring the data image. An implementation of tailoring the data image based on the preset size may further be: the electronic terminal determines a central location of the data image based on a distribution status of the graphic element in the data image, and tailors the data image by using the central location as a preset coordinate point of the wallpaper. The preset coordinate point may be a geometric center of the wallpaper, or may be a golden section point of the wallpaper, or the like. For example, the electronic terminal may perform tailoring by using a location of a graphic element of a maximum size as the central location, or using an area with the densest graphic elements as the central location. Optionally, the central location may be used as the golden section point of the wallpaper, and the golden section point is an intersection point of a golden section line in a vertical direction of the wallpaper and a golden section line in a horizontal direction of the wallpaper.

Referring to FIG. 9, FIG. 9 is a schematic diagram of first wallpaper according to an embodiment of the present invention. FIG. 9 is the wallpaper tailored from the data image shown in FIG. 3. Specifically, an area with the densest high-brightness points is used as the central location, the central location is used as the golden section point of the wallpaper, and tailoring is performed based on the size of the display screen. When the target data changes, a size of a corresponding circle in the wallpaper dynamically changes, and the central location of the data image varies with the size of the circle. Therefore, a data image area displayed in the wallpaper also dynamically changes.

Referring to FIG. 10, FIG. 10 is a schematic diagram of second wallpaper according to an embodiment of the present invention. FIG. 10 is the wallpaper tailored from the data image shown in FIG. 4.

Referring to FIG. 11, FIG. 11 is a schematic diagram of third wallpaper according to an embodiment of the present invention. FIG. 10 is the wallpaper tailored from the data image shown in FIG. 5.

Referring to FIG. 12, FIG. 12 is a schematic diagram of fourth wallpaper according to an embodiment of the present invention. FIG. 10 is the wallpaper tailored from the data image shown in FIG. 6.

Referring to FIG. 13, FIG. 13 is a schematic diagram of fifth wallpaper according to an embodiment of the present invention. FIG. 10 is the wallpaper tailored from the data image shown in FIG. 7.

Referring to FIG. 14, FIG. 14 is a schematic diagram of sixth wallpaper according to an embodiment of the present invention. FIG. 10 is the wallpaper tailored from the data image shown in FIG. 8.

It may be understood that image elements in the wallpaper shown in FIG. 10 to FIG. 14 dynamically vary with the target data.

In this embodiment of the present invention, before step S210, the data processing method may further include: receiving an input screen wakeup operation, where the screen wakeup operation is used to trigger to enter a lock screen interface; and correspondingly, after step S230, the data processing method may further include: displaying the wallpaper in the lock screen interface.

The screen wakeup operation may be pressing a power button, a double-tap operation on an electronic terminal touchscreen, or the like. In the technical solution, the electronic terminal obtains the target data only when receiving the input screen wakeup operation, converts the target data into the data image by using the data visualization technology, sets the data image as the wallpaper, and displays the wallpaper in the lock screen interface. This avoids high energy consumption caused by real-time processing of the target data by the electronic terminal.

In this embodiment of the present invention, the electronic terminal may refresh the target data once every preset time period, for example, refresh the target data once every 20 minutes, 60 minutes, one day, or the like. Alternatively, the electronic terminal may refresh the target data once when detecting a preset operation, and the preset operation may be the screen wakeup operation, a tapping operation, a double-tap operation, a sliding operation, a touch and hold operation, or the like for the data image in the home interface or the lock screen interface of the electronic terminal, so that the data image dynamically varies with update of the target data, and at the same time, high energy consumption caused by real-time update of the target data by the electronic terminal is avoided.

In another embodiment of the present invention, the target data may also be displayed in a form other than the wallpaper, for example, a matter notification that the user may be concerned about, a to-do reminder obtained by analyzing based on a behavior habit of the user, pushing of content (an image, a text, an APP, music, and the like), recommendation of a similar friend, and the like.

In this embodiment of the present invention, the electronic terminal obtains the target data that includes the at least one data item, converts the target data into the data image by using the data visualization technology, and then sets the data image as the wallpaper, where the data image includes the at least one graphic element, and the graphic element is in a one-to-one correspondence with the data item. The target data is the user data, and may include the operation event information of operating the electronic terminal by the user, or the information that is associated with the user account and that is based on the at least one network platform, so as to automatically generate the wallpaper and improve user experience.

In addition, the user data may be displayed by using the wallpaper, and the wallpaper dynamically varies with update of the user data.
